ing Apparatus, of which the following is a` specification.

This invention relates broadly to loading apparatus, and morespecifically to a powerdriven shovel and conveyer for loading coal andlike materials in cars or the like. j

lThe primary object of the invention is to provide an efficientapparatus whereby materials, such as coal, may be rapidly loaded uponcars for transportation, and which is especially adapted for use inmines.

A further object is to provide a powerdriven apparatus of the charactermentioned which is automatic in its operation, lwhich is strong anddurable in its construction, have' ing but'few parts liable to becomeout of order, and lwhich may readily be shifted from place to place asoccasion requires.

l/Vith these and other important objects in view, the invention residesin the features of construction, arrangement of parts and.

combinations of elements which will hereinafter be exemplified,reference belng had to the'accompanying drawings, 1n which- Figure 1 isa side elevation of the inven tion;

Fig. 2 is a front end elevation; Fig. 3 is a rear end elevation; Fig. 4is a top plan View; Fig. 5 is an enlarged section taken substantially online 5 5, Fig. 4;

' reverslng gear.

Fig. 6 is a side. elevation of the front end portion of the machine,showing vario-us positions assumed by the shovel; and- Fig. 7 is anenlarged detail section of the Referring Ato said drawings, which likedesignating characters distinguish like parts throughout the severalviews- 1 indicates a large gear which is mountedl horizontally beneaththe upper part, as-the platform 2, ofa truck-carried fran 1e;sa1d gearbeing keyed or splined upon and rotatable with an upright pin or shaft 3whichhas its lower end suitably disposed, as in a j portion 4 -of'thetruck frame .whlch underlies said gear 1, the latteibeing spaced awayfrom said portion '4 andpsupported by a suitable'bearing-like washer 5within which resting upon the end of the latter is one end of acrank-arm 7 whichA has its opposite end pivotally connected to the rearend of a con` necting rod or pitman 8 .which has its front end connectedpivotally to a horizontally ldisposed carriage 9. The crank-arm 7 isinterlocked with said huby'6 in a suitable manner, as by a downwardlyprojecting stud or pin 10 carried by said arm and seated in a socket 11provided therefor in the end of said hub.

Said carriage 9 is longitudinally slidable over parallel gibs 12 0r uponthe front end of an underlying turn-table 13 which carries said gibs.Said turn-table overlies and has rotary movement upon or with respect toa plate or table 14,-herein depicted as of circular form, which isrigidly mounted upon the truck platform 2; Said turn-table has'adownwsadly-extending hub 15 disposed for rotary movement about the hub 6of gear 1.

The carriage 9 is disposed between said gibs 12 which have theiropposing faces undercut to form guideways 1 6 in which portions of saidcarriage are received, tipping vor overturning movement of said carriagebeing thus effectually prevented.

Mounted upon said carriage 9 are suitable l bearings, as ,17, in whichis journaled a effecting rotation of said Wheels.

Extending diamet'ricallyV across the outer face of each wheel 19 andeither fixed to or formed lntegral with such wheel is a crosshead orcrank 22 which vcarries at one end a crank-pin 23 upon .which is pivotedthe rear end of an arm 24.l The front ends of the oppositearms 24 arepivotally mounted upon trunnions 25 carried by the opposite sides 26 ofa shovel or yscoop which is generally designated by the reference letterA and which lll@ 25 drive-shaft of an appropriately located elecshown.

Disposed in meshing relation`tothe. gear 1 is a pinion 29 Xed upon anupright shaft journaled in suitable bearings carried by the frame and inan upright sleeve-bearing 31 mounted upon the top of said frame. Fixedupon the upper end of said shaft 30 is a bevel-'gear 32 adapted to beoperatively' engaged by one or the Aother of two oppositely facingbevel-gears 33. and 34 accord ing as it is required to drive onedirection or the other. Said gears 33 and 34 are fixed upon a shiftablesleeve 35 and are spaced apart such a distance that they cannotsimultaneously engage the bevel gear 32. Said sleeve 35 is keyed uponand shiftable along a transverse shaft 36 journaled in I suitablebearings, as 37, carried by upright frame members 38 mounted upon theplatform 2-or other suitable portions of the truck frame. A spur gear 39carried by said shaft 36 has disposed in driving relation thereto aIpinion 40 carried by the tric motor 41.

Associated with the sleeve 35 is suitable means, as the connectedpivotally mounted lever members 42 and 43, whereby shifting of saidsleeve in either direction may be.

accomplished.

Disposed in a suitably elevated position, as upon theframe members 38,are the side members of a rectangular boX-like inclosure 442tconstituting a part of a conveyer which is herein designated generallyby the numeral 44. Said conveyer has the forward portion thereofdisposed in overhanging relation to the truck platform 2 and tohereinbefore described mechanism carried by saidplatform, and the rearend of said conveyer extends. rearward from its supports and withrespect to therear end of the truck by which said supports are carried,so that it may occupy a position overlying or overhanging. be loaded, asis best shown in Fig. 1. A plurality of transverse rollers 45 arelocated -within the inclosure 44, the same having their shafts suitablyjournaled, as in the side members of said inclosure. Mounted on saidrollers to be actuated by the latter is an endless traveling conveyer orapron 46 upon frwhich the material being loaded is dumped from the'shovel and by which said material is carried rearward and dumped into acar overhung by the rear end of said conveyer.

Power forproducing travel of the apron 46 may be applied in anyappropriate manner, as by a sprocket chain 47 connecting a sprocketwheel 48 on the end of the shaft of one of the rollers 45 to a sprocketwheel 49 carried by the shaft 36.

For changing the direction of the thrust said shaft in part of the a caror the like to,

of the shovel to any desired angle with respect to the longitudinal lineof the machine, the turn-table 13 is made laterally shiftable. Aworm-gear 50 is mounted to rotate on the hub 6 of gear 1 .and is fixedto said turn-table, as by means of bolts 51. A worm 52 carried by atransverse shaft 53 is operatively engaged with said worm-gear. Saidshaft is located rearward with respect to said worm-gear and is ournaledin bearings, as 54, mounted onthe truck platform 2. While said shaft'may be driven in any suitable manner for accomplishing rotation ,of theturn-table for shifting the shovel laterally, ll prefer to employ asprocket wheel 55 located on said shaft, and to connect the same bymeans of a sprocket chain 56 to a sprocket wheel 57 which is rotatablymounted on an end of the shaft wheel `has a dentated hub 57.a adapted tobe operatively engaged by a correspondingly dentated clutch-member 58which is mounted on said shaft 36 and which is adapted to be 36. Saidsprocket shifted into and out of interlocking relation the other lationto the bevel gear 32 according as it is desired to rotate the shaft in aforward or reverse direction. explained, the shovel anism are operablewith equal facility irrespective of the direction of rotation of saidshaft 36. Motion imparted to said vbevel gear 32 is communicatedthroughthe shaft 30 andthe pinion 29 to the large gear 1,

.thence through the hub 6 of the latter to the crank-arm 7, pitman 8 andcarriage 9,

the latter being actuated to move back andl forth in a reciprocatorymanner between vthe glbs 12 located on the front end of the turntable13. With such movement of the carriag'e 9, the wheels 19 tf'avel backand forth upon the trackways 20, rotation as distinguished from slidingmovement?` of said wheels belng insured by the inter-engagement of thespurs 19a thereof withA the seats or `holes21 provided in saidtrackways.

Rotation of said wheels 19 in a forward,

direction actuates the shovel A to advance, and vice versa. Forwardrotation of said wheels following that in which the shovel initiallyseats upon the ground or floor,

shown in full lines in Fig. 6, results in said shovel being advancedalong saidV ground or floor to or toward the forward dotted-lineyposition shown in said figure for scooping As will hereinafter be andits actu-atin g mechmeager Awheels 19, until it reaches said initialseating position, whereupon the under'sides of 'the inclined shovel arms24 engage laterally projecting fulcrum-pins 60 carried. by ends of thecross-head-like cranks 22 opposite the ends thereof whichcarry thecrank-pins 23. Continued rearward rotation of said wheels 19 results insaid arms 24 and the loaded shovel. being elevated from said initialshovel-seating position to the substantially upright position shown indotted lines in Figs. 1 and 6, and in full lines in Figs. 2 and 3. Slihtly prior to said position `being reache an arm 61 carried by the back28 of the shovel engages an arcuately curved outstanding horizontalmember or rim 62 carried by the front end of the box-like inclosure 44aof the conveyer, whereby said shovel is swung to the rearwardly tippedposition shown for dumping its contents upon the forward end of theapron conveyer 46 by which said contents are conveyed rearward, ashereinbefore described.

|The, final shovel-dumping position is assumed when the crank-arm 7 andthe pitman 8 occupy their rearmost positions with the latter overlyingand in parallel alinement with the former. Consequently, continuedrotary movement of 4the last-mentioned parts serves to reverse thedirection of movement. of the carriage 9 and the wheels 19 whereby theshovel is returned to its initial seating position and is thence againthrust 'forward into the bank or pile of material, as

aforesaid. rThus, as is apparent, uninterrupted operation, withoutreversal of the mechanism which effects reciprocation of theshovel-carryihg mechanism is permitted. Further, when in the operationof the shovel, the same may be advantageously advanced into the bank orpile of material to the limit of its forward movement, thereciprocationproducing mechanism may be driven uninterruptedly, orwithout reversal, it being obvious that, when the shovel has reached thelimit of its forward travel, the crank-arm 7 and pitman 8 occupypositions in extended alined relation, and that continued movement willact to return the shovel in rearward direction. However, when it isimpracticable to advance the shovel to the limit of its forwardmovement, as when the bankl or pile of material to be handled lies closeto the initial shovel-seating position so that the shovel receives itsload with a thrust short of that of which it is capable-that is, with 4afractional part of the possible thrustthe sleeve 35 is shifted on theshaft 36 in the manner hereinbefore indicated to effect a reversal ofthe direction of rotation of said shaft and," consequently, of themechanism intermediate said shaft and the carriage 9 for moving thelatter rearward, thus accomplishing retraction of said shovel. Suchreverse movement of said mechanisms will be continued until the shovelis again loaded, whereupon the sleeve 35 may again be shifted to effectretraction thereof, and so on,

To prevent rearward tipping or dumping movement of the shovel while itis being retracted to the point where elevation thereof begins,rearwardly extending bracing members, as 26, preferably constitutingeXtensions of the shovel sides 26, are provided. On the other hand, toprevent forward tipping of the shovel which would result in discharge ofits load during elevation thereof, fulcrum pins, as 63, are suitablylocated on said members 26a for assuming underlying engagement with theshovel arms 24 at the moment when elevating movement commences.

Angular members or feet 64 are preferably carried by the rear ends ofthe shovel arms 24 in a position for seating upon the platform 2 toprevent rearward tilting movement of said arms beyond the requisitesubstantialiy upright position assumed by the latter when shovel-dumpingposition is reached.

e As is obvious, the carriage 9 may be wholly supported by the shaft 18Vupon which the wheels 19 arev mounted, or it may be supported by andhave sliding movement on the gibs 12. In the latter case said wheelsserve merely as shovel-actuating elements.
